Your [`Renderer`] is responsible to render the +previously processed frames onto the screen. + +By calling [`yourRenderApiSender.create_api()`](api::RenderApiSender::create_api), you'll +get a [`RenderApi`](api::RenderApi) instance, which is responsible for managing resources +and documents. A worker thread is used internally to untie the workload from the application +thread and therefore be able to make better use of multicore systems. + +## Frame + +What is referred to as a `frame`, is the current geometry on the screen. +A new Frame is created by calling [`set_display_list()`](api::Transaction::set_display_list) +on the [`RenderApi`](api::RenderApi). When the geometry is processed, the application will be +informed via a [`RenderNotifier`](api::RenderNotifier), a callback which you pass to +[`Renderer::new`]. +More information about [stacking contexts][stacking_contexts]. + +[`set_display_list()`](api::Transaction::set_display_list) also needs to be supplied with +[`BuiltDisplayList`](api::BuiltDisplayList)s. These are obtained by finalizing a +[`DisplayListBuilder`](api::DisplayListBuilder). These are used to draw your geometry. But it +doesn't only contain trivial geometry, it can also store another +[`StackingContext`](api::StackingContext), as they're nestable. + +[stacking_contexts]: https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Positioning/Understanding_z_index/The_stacking_context +*/ + +#![cfg_attr(feature = "cargo-clippy", allow(clippy::unreadable_literal, clippy::new_without_default, clippy::too_many_arguments))] + + +// Cribbed from the |matches| crate, for simplicity. +macro_rules! matches { + ($expression:expr, $($pattern:tt)+) => { + match $expression { + $($pattern)+ => true, + _ => false + } + } +} + +#[macro_use] +extern crate bitflags; +#[macro_use] +extern crate lazy_static; +#[macro_use] +extern crate log; +#[macro_use] +extern crate malloc_size_of_derive; +#[cfg(any(feature = "serde"))] +#[macro_use] +extern crate serde; +#[macro_use] +extern crate tracy_rs; +#[macro_use] +extern crate derive_more; +extern crate malloc_size_of; +extern crate svg_fmt; + +#[macro_use] +mod profiler; +mod telemetry; + +mod batch; +mod border; +mod box_shadow; +#[cfg(any(feature = "capture", feature = "replay"))] +mod capture; +mod clip; +mod space; +mod spatial_tree; +mod command_buffer; +mod composite; +mod compositor; +mod debug_colors; +mod debug_font_data; +mod debug_item; +mod device; +mod ellipse; +mod filterdata; +mod frame_builder; +mod freelist; +mod glyph_cache; +mod gpu_cache; +mod gpu_types; +mod hit_test; +mod internal_types; +mod lru_cache; +mod picture; +mod picture_graph; +mod prepare; +mod prim_store; +mod print_tree; +mod render_backend; +mod render_target; +mod render_task_graph; +mod render_task_cache; +mod render_task; +mod renderer; +mod resource_cache; +mod scene; +mod scene_builder_thread; +mod scene_building; +mod screen_capture; +mod segment; +mod spatial_node; +mod surface; +mod texture_pack; +mod texture_cache; +mod tile_cache; +mod util; +mod visibility; +mod api_resources; +mod image_tiling; +mod image_source; +mod rectangle_occlusion; +mod picture_textures; + +/// +pub mod intern; +/// +pub mod render_api; + +pub mod shader_source { + include!(concat!(env!("OUT_DIR"), "/shaders.rs")); +} + +extern crate bincode; +extern crate byteorder; +pub extern crate euclid; +extern crate fxhash; +extern crate gleam; +extern crate num_traits; +extern crate plane_split; +extern crate rayon; +#[cfg(feature = "ron")] +extern crate ron; +#[macro_use] +extern crate smallvec; +extern crate time; +#[cfg(all(feature = "capture", feature = "png"))] +extern crate png; +#[cfg(test)] +extern crate rand; + +pub extern crate api; +extern crate webrender_build; + +#[doc(hidden)] +pub use crate::composite::{CompositorConfig, Compositor, CompositorCapabilities, CompositorSurfaceTransform}; +pub use crate::composite::{NativeSurfaceId, NativeTileId, NativeSurfaceInfo, PartialPresentCompositor}; +pub use crate::composite::{MappableCompositor, MappedTileInfo, SWGLCompositeSurfaceInfo, WindowVisibility}; +pub use crate::device::{UploadMethod, VertexUsageHint, get_gl_target, get_unoptimized_shader_source}; +pub use crate::device::{ProgramBinary, ProgramCache, ProgramCacheObserver, FormatDesc}; +pub use crate::device::Device; +pub use crate::profiler::{ProfilerHooks, set_profiler_hooks}; +pub use crate::renderer::{ + CpuProfile, DebugFlags, GpuProfile, GraphicsApi, + GraphicsApiInfo, PipelineInfo, Renderer, RendererError, RenderResults, + RendererStats, Shaders, SharedShaders, ShaderPrecacheFlags, + MAX_VERTEX_TEXTURE_WIDTH, +}; +pub use crate::renderer::init::{WebRenderOptions, create_webrender_instance, AsyncPropertySampler, SceneBuilderHooks, ONE_TIME_USAGE_HINT}; +pub use crate::hit_test::SharedHitTester; +pub use crate::internal_types::FastHashMap; +pub use crate::screen_capture::{AsyncScreenshotHandle, RecordedFrameHandle}; +pub use crate::texture_cache::TextureCacheConfig; +pub use api as webrender_api; +pub use webrender_build::shader::ProgramSourceDigest; +pub use crate::picture::{TileDescriptor, TileId, InvalidationReason}; +pub use crate::picture::{PrimitiveCompareResult, CompareHelperResult}; +pub use crate::picture::{TileNode, TileNodeKind, TileOffset}; +pub use crate::intern::ItemUid; +pub use crate::render_api::*; +pub use crate::tile_cache::{PictureCacheDebugInfo, DirtyTileDebugInfo, TileDebugInfo, SliceDebugInfo}; +pub use glyph_rasterizer; + +#[cfg(feature = "sw_compositor")] +pub use crate::compositor::sw_compositor; |
